Any such corporation shall have the right to acquire real estate, or any interest therein, necessary for the purposes of its incorporation, and the right to lay, repair and maintain conduits and sewer pipes with connections and fixtures, and other necessary portions of the system, in, through or over the lands of others. If any such corporation, authorized by this article shall be unable to agree upon the terms of purchase of any such property or rights, it may acquire the same by condemnation. Notwithstanding the foregoing, in Suffolk county such corporation shall not have the right to condemn or use the land of others without first obtaining the prior written consent of the county sewer agency and the department of environmental control.
